For the reseller

Sinocastel: the same manufacturer as Castel, and the same business

Sinocastel and Castel are the same house: a Chinese manufacturer founded in 1997 and linked to the country's state aerospace group. Its speciality is devices that plug into the vehicle's diagnostic port.

Who you sell it to: vehicle rental, usage-based insurance and customers who will not let anyone touch the car.

What it earns you: installation without a technician. The customer plugs it in himself, so you can sell into another city without sending anyone. That is what lets you grow without hiring.

What to watch: it comes out as easily as it goes in. Do not sell it as anti-theft. And look for documentation under both names — both circulate.

Where the connector device fits: vehicle rental, tracking with no hardware and what to charge and how often.

Which protocol it speaks: Sinocastel devices reach the platform over the Castel and Conector OBD protocols. Their pages explain what they are and how they work.
